The greatest explorers in the world come from the Pathfinder Society, a motley assembly of adventurers, archaeologists, and mystics who brave the lost cities and forgotten dungeons of the world in search of treasure, knowledge, and the thrill of discovery. This comprehensive guide to the Pathfinder Society provides an exciting overview of the world-spanning organization, with extensive explorations of its history, customs, bylaws, goals, and machinations. A sample, fully mapped Chapter House and fully detailed Pathfinder Society characters make it easy for players and game masters to add the organization to their games, either as patrons, allies, or foils.
